Interval – the Interval program changes "Speed" to raise your heart rate for a short period and
then reduces the speed to bring your heart rate back down again. The starting and
maximum speeds vary depending on the level that you chose but range from a starting speed of
1 MPH in Level 1 to 4 MPH in Level 5. At each level, the speed will increase by 3 MPH during the
sprint portion of the interval. The length of the sprint period will depend on the length of the
workout that you choose.
Hill Climb – the Hill Climb program lets you set the Speed that you want to walk or run and
adjusts the Incline to increase and decrease the intensity of the workout. At Level 1 the incline
ranges from 1 to 6 degrees and at Level 5 it varies from 5 to 10 degrees. This program tends to
keep the level of Incline higher than the "Weight Loss" program and is an effective program to
improve strength.
Weight Loss – the Weight Loss program is similar to the Hill Climb program in that they both
vary the incline and keep the speed constant. The difference in this program is that rather than
being set for a specific time period, the workout is based on distance. During
Set-up, the Level that you pick determines how far you need to walk or run until the program
is completed. The distance ranges from 3 miles in level one to 11 miles in level 5.
